I need to sample a signal of 40MHz with a sampling frequency of 120MHz at least with a 8/12 bits ADC and send them through the USB serial port of a PC. That means the serial communication bandwith should be at least 960/1440 megabits per second.
What kind of DSP should I use to satisfy this bit-rate, and what signal-processing-methods should I learn to optimize this bit-stream to use the same data simultaneously with a mainstream PC. (The bitrate seemed a bit huge for me.)
I have no experience with DSPs before. I was seeking for answers for a while but not even my teachers, or their assistants could help me for a little long period of time.
I just need a beacon to find the answers of the questions, thanks in advance.
Edit: I wrote 40Hz instead 40MHz, I am really sorry.
